mn'rnon O1 MM'UFACTURING SHOES.

Be it known-that we, PATRICK J. BYRNES and BENJAMLNB. OSBURN, citizens of the United States, residing at Rochester, in the county of Monroe and State'of New York, have invented certain new and useful Improvements in Methods of Manufacturing Shoes, of which the following'is a specifica tion, reference being had therein to the accompanying drawing. m

This invention relates to a novel method of manufacturing shoes, and pertains particularly to the sole used in the above method. y I

' The primary object of this invention is to last an upper which has attached thereto a welt on a last without the usual insole and then to remove the lasting tacks and cement a thin sole to the welt, and to subject said thin sole to pres'sure'to form a recess within which the bottom filler-can be placed and the shoe, and

to attach the outsole by means of stitching passing through the edges of the outsole, insole and welt.

In the accompanying drawing- Figure 1 is a longitudinal "sectional view] of a shoe made according toour improved process.

Fig. 2 shows the first step of the shoe.

Fig. 3 is the" second step in the making of the shoe.

Fig. 4: is the third step in the making of in the making Fig. 5 is the the shoe. a

In carrying out the improved process an a welt 2 at 3. The u per with the welt stitched there-' to is next talien and lasted by means of tacks 5 to a last 4 which comprises the first step in the process.

The second step of the improvement 1s to remove the tacks and leave therein three headless tacks 6 to hold the upper and welt fourth step in the makin of to the last, and these headless tacks are adapted to come out with the last when it Is pulled out. We

thus have a shaped upper with only the Welt attached thereto.

\Vhen the shoe is to be completed, a straight flat sole 7 is cemented to the outer Specification of Letters Patent.

- or bottom face of the welt 2 of the upper which is on the last, and this sole may be termed as the thin outer sole, because it is applied to the outer or bottom face of the welt 2. This thin sole 7 is then pressed-inwardly by a suitable mechanism (not here step 1n carryingout the present improvement. I

With the thin sole 7 cemented to the welt andpress'ed inward to form the recess 9, as

able bottom filler 11, and the filling of this urecess with the bottom filler is the fourth step of the present improvement.

The final step of this improvement is atdescribed, it is then ready to receive a suit- 3 .taching the outer sole 12 outside of the thin sole7 to the welt 2, by the usual stitching 13. Of course the heel in childrens shoes structionhas two soles applied to the outer.

or bottom face of thewelt 2;'and the inner one 7 pressed inward to perform the function and to have the appearance of the ordinary inner sole.

' This improvement eflects economy in labor and material over the ordinary way of constructing shoes with the ordinary inner sole applied in theusual manner.

In-the manufacture of the shoe, according tothe present invention, the thin sole 7 when cemented to the-welt 2 is flat and damp and then ressed inward as shown in Fig. 4, and permitted to dry. After it has dried in this pressed position, the filling 11 is placed in the cavity 4 formed by the depressing of the V I -will be built up by a suitableqfi ller .14, prefthin sole 7, and then the outer sole isplaced in ositionand attached as above described.
